Climate is too important in our lives to be excluded from a book about human environment. It is something that practically everyone is aware of and that many people consider very important. It is not only in the realm of high science but in everyday consciousness that climate has a part to play. The Tower of the Winds (or Temple of Aiolos) in the Roman agora in Athens, built in the ﬁrst century AD, depicts representations of the winds in reliefs around its eight sides (Figure 5.1). It was created as a meteorological station and clock, and is one of the earliest indications of an interest in climate in the western world.
